Insecure service configuration - LDAP

Description​

Internal service information should not be stored in the source code, especially AD configurations, as it is obtained from the admon-chanel configuration file.

Impact​

Use these insecure service configurations to gain access to the AD and collect all kinds of information that will be useful in later attacks, such as internal network architecture recognition or employee information.

Recommendation​

Service configurations and credentials must be in protected environments.

Threat​

Internal attacker with access to service configurations.

Expected Remediation Time​

⌚ 60 minutes.

Code Examples​

Compliant code​

Sensitive resources do not have their credentials stored in the source code

using System;
class cipher{
  public void Encrypt() {
    DirectoryEntry thrdDirectoryEntry = new DirectoryEntry(adPath, "u", "p", AuthenticationTypes.Secure);
  }
}

Non compliant code​

There is sensitive information store as plain text

using System;
class cipher{
  public void Encrypt() {
    DirectoryEntry myDirectoryEntry = new DirectoryEntry(adPath);
    myDirectoryEntry.AuthenticationType = AuthenticationTypes.None;
    DirectoryEntry sndDirectoryEntry = new DirectoryEntry(adPath, "u", "p", AuthenticationTypes.None);
  }
}
